ICD-10 Code D89.813 – Graft-versus-host disease, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D89.813 – Graft-versus-host disease, unspecified
What it is
D89.813 identifies graft-versus-host disease when the record does not specify acute, chronic, or another subtype. It means donor immune cells are attacking the recipient’s tissues after transplant.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings may include skin rash, gastrointestinal symptoms, liver involvement, or other transplant-related immune injury.
When to use this code
Use D89.813 when the provider documents graft-versus-host disease but does not identify a more specific type. It is appropriate for transplant follow-up notes, consults, or problem lists that clearly state GVHD without further detail. If the record later specifies acute or chronic disease, code the documented subtype instead.
Do not use for
Do not use this code when the chart specifies acute or chronic graft-versus-host disease. Also avoid it if the note only describes transplant complications without confirming GVHD; check documentation.
Coding tip
Code the most specific GVHD type documented; use D89.813 only when the subtype is not stated.
